“Quick question? How are you amplifying the EEG signals before feeding them into the arduino? I ask because all of the neuroscience researchers I’ve talked to say you need an amplifier roughly the size of a VCR to bring the signals up to levels at which they can be analyzed. If you’ve found a way to just plug wires from the electrode pads into the analog inputs on an arduino that would be quite the breakthrough. Also is there any chance you’d be willing to demo your code for separating the brain activity on the EEG from noise created by environmental effects and muscle movements since I’m sure you know that something as small as an eye blink creates an electrical impulse at the scalp which dwarfs the majority of the brain’s electrical signals when measured through the skull. “

Unlike the other post that we made about brain-controlled devices using an Emotiv headset, this one claims to recognize different words.

They outfitted volunteers with caps with EEG sensors, and asked them to steer a helicopter on a computer screen through a series of randomly generated rings that appeared on the screen ahead of it. There were no hand controls, no joysticks. They could only try to will the helicopter forward with their minds.
